Blockchain Basics

Buffalo introduces blockchain through its structure, algorithms and trust model. Ethereum provides a technical context before later smart-contract work in the sequence. The course is labeled beginner, but the provider explicitly expects knowledge of a modern high-level programming language.

What you will learn

• Explain the structure of a blockchain.
• Describe Ethereum’s role in the course examples.
• Connect supporting algorithms with distributed trust.

Who this suits

Learners who know at least one modern high-level programming language, following the provider’s prerequisite.

Before you enroll

Separate the technical curriculum from claims about asset prices or investment returns. Platforms, security practices and regulation change, so check the age of examples. Use a local development environment or test network for exercises involving transactions.

Coursera offers paid enrollment or subscription access. Check the enrollment screen for assessment and certificate terms, trials and any financial-aid options. Provider access terms can change; review them before paying.

Put it into practice

Draw a small fictional chain of records and explain what changes when an earlier record is altered.
